Reactions of 4-morpholino-1,2-naphthoquinone with enamines ando-phenylenediamine
摘要:
The reactions of 4-morpholino-1,2-naphthoquinone with enamines, cyclohexanone derivatives, afford 7a-amino-5-morpholinohexahydrobenzo[b]naphtho[1,2][1.4]dioxines. while the reaction with o-phenylenediamine yields 5-morpholinobenzo[a]phenazine.
